SECTION 8 - AIRPLANE HANDLING, SERVICING, AND
The Safe Flight AoA indicating system is not field repairable. If the
operation of the system is in doubt, apply power to the system and verify that
the power-on self-test has completed properly. If the power-on self-test is
unsuccessful, hold the top and bottom buttons on the AoA Indicator for two
seconds while power is applied. The display will illuminate all reference marker
segments and then will illuminate a particular light segment on the display. Note
which light segments illuminated, as this will aid in diagnosing the problem.
When contacting support, have the following information available:
l. Unit part number
2. Unit serial number
3. Unit software revision
4. Fault code (which LEDs illuminated on the display)
•
The pa.rt number, serial number, and software revision can be found on the
nameplate on the lower surface of the AoA Indicator. Detaching the unit is not
necessary as the values can be seen with the aid of a mirror or by taking a picture
with a slim camera.
